Book Reviews of Understanding Digital Signal Processing (2nd Edition)

Book Review: This book is well written, its informative and interesting.
Summary: 5 Stars

I had seen the book "Understanding Digital Signal Processing" by Richard G. Lyons advertised on the internet. I have also seen and read several technical articles authored by Lyons scattered around the internet. I was interested in the book but I didn't want to purchase it before I could thumb through it and get an idea of the quality of its content. I paid a visit to the well stocked library at Embry Riddle Aeronautical University and found it sitting on the shelf in the signal processing section. I checked the book out and had three weeks to read and evaluate it. I was not able to read the entire book in the three week period but I read enough in about two weeks to determine that it was a well written book so I ordered a copy from Amazon.

Lyons states in the book's introduction "I've attempted to avoid the traditional instructor-student relationship, but rather make reading this book like talking to a friend while walking in the park". I believe Lyons has achieved his goals in this respect.

In my grad and under grad days, in order to gain some understanding of the subject at hand, I spent many an hour reading and then re-reading course assigned engineering texts in an effort to fill in the many technical blanks left by the authors. A large majority of these texts took a stuffed shirt approach in what seemed to be a pompous attempt by the author to demonstrate his intelligence. They rarely connected all the technical dots. Now that I think about it, a bunch of the dots were missing too!

Attitudes like this seem to changing with modern day authors like Lyons. He makes a noticeable effort to keep the material informative and interesting. I really appreciate the fact that Lyons takes his time and thoroughly explains each subject. He uses a lot of text to walk the reader through each topic.

In his presentation he fills in the critical blanks and eliminates a great deal of the classical stumbling blocks that usually led to student head scratching, wall pounding , and dog kicking, which was a common reaction to the older generation texts.

This is definitely a good book for engineering students who have just begun their journey into the world of Digital Signal Processing. This is definitely a good book for practicing engineers who feel the need to clear up some of the gray areas in their DSP knowledge.

The title of the book "Understanding Digital Signal Processing" pretty much lets the buyer know right from the start that the content of the book is targeted at engineers with a beginning to intermediate knowledge of DSP. This book is probably not suited for the engineering guru's with 20 or 30 years experience in the field of DSP. However, I bet there is some information contained in Lyons work that will clear a few of the technical cobwebs from even these people's heads.

Lyons starts off with a few chapters on the Discrete and Fast Fourier Transform, and finite impulse response and infinite impulse response filters just like most DSP texts. Then he departs from the normal course DSP texts seem to pursue and he takes a step towards real world DSP applications with chapters on quadrature signals, the discrete Hilbert transform, sample rate conversion and signal averaging. He spends a chapter on data formats and their corresponding attributes, which sounds dull until the day you find yourself tasked to design a digital processor that performs high speed digital computations. He then spends more than 100 pages on tips and tricks that are useful in many common signal processing applications.

I received my copy of Lyons book from Amazon last week and am in the process of reading the remainder of the book. When I am done this book will occupy a prime space in my office book case, right at eye level, for an easy grab when needed.

After having read much of the book, would I spend the money to purchase it again if necessary? The answer is a definite yes. This is money well spent.

Summary of Understanding Digital Signal Processing (2nd Edition)

The effects of DSP has entered every phase of our lives, from singing greeting cards to CD players and cell phones to medical x-ray analysis. Without DSP, there would be no Internet. In recent years, every aspect of engineering and science has been influenced by DSP because of the ubiquitous desktop computer and readily available signal processing software. This book provides engineers and scientists, who are relative beginners to DSP, their best opportunity to learn the basic mathematical and practical-engineering aspects of the burgeoning field of DSP. The book strikes the right balance of mathematical level, and practical engineering guidance, making it accessible to the beginner without dumbing down the topic of DSP. This edition of Understanding Digital Signal Processing will continue bridging the gap between DSP theory and practice. The presentation of additional quadrature processing material makes the book more relevant, and useful, to DSP practitioners in the burgeoning fields of digital communications and wireless networking systems. The new digital filtering material covers modern filter design techniques not covered in our competitor's books. Finally, the popular 'Digital Signal Processing Tricks' material will be expanded to further aid working DSP engineers solve their day-to-day signal processing problems as they design and build commercial products and aerospace systems.
